Regarding steering wheel controls, I've used both the PAC SWI-JACK and the Metra Axxess ASWC to retain my factory steering wheel controls with a new head unit. Of the two, I recommend the Metra Axxess ASWC as it's a) less work to install in terms of things you must access on the truck and wires you must find, b) self-programming, and c) reliable. I can say none of those things for the PAC SWI-JACK as it pertains to use with a Kenwood head unit.

Like you I have an 04 that had Bose and OnStar. I completely removed the Bose system so I needed the chime module and used PAC OS-2CBOSE, which worked (and is still working) just fine.

Good thread. I'll hopefully be upgrade my head unit, and crutchfield recommends the PAC. I'll have to look into the other you mentioned Surreal. Ease of installation is definitely a factor to consider.
